STUD ENT-LAM P.

SPECIFICATION forming part of Letters Patent No. 223,216, dated January 6, 1880.

Application filed April 2B, 1879.

To all whom it may concern Be it known that I, SETE O. CATLIN, of Brooklyn, in the State of New York, have invented an Improvement in Student-Lamps, of

which the following is a specification.

Lamps have been made with a stationary wick and a movable wick, so that the wick that is consumed may receive its supply of oil from the stationary' wick. Studontlamps have also been supported by a standard run ning down into a tube in the base.

In my lamp the tubular standard is peculiarly constructed to obtain rigidity with the greatest extent of vertical movement, the wick is adjustable from the dripcup or from the chimney-holder, so as lo regulate the tlame with facility, and the movable wick is outside of a stationary capillary wick, so that the wick for the flame will be more uniformly supplied with oil.

In the drawings, Figure 1 is a vertical section of the lamp-burner and its stand, and Fig. 2 is a detached elevation of the upper part of the wick-raising sleeve.

The fountain and reservoir b are to be of the usual character in studentlamps, and the pipe c extends from the bottom ot' the reservoir to the burner-tube d. Beneath this tube o is the supporting-rod cl, that has a head, 2, 3o at the lower end. It passes through the collar e, that is screwed into the upper end of the tubular standard f. This tube f extends through the weighted base or foot g, and nearly touches the table or surface upon which the lamp stands. The length of the rod d is such that its head 2 cannot descend belowl the lower end of the tube f; hence it cannot be caught against that end, but it always slides freely within the tube and steadies the lower end ofthe rod d', and this rod d cannot be accidentally drawn out ofthe standard f because of the collar e. A clamping-screw, It, supports the lamp, in whatever position it maybe placed, by raising the rod d.

The cup ciis rigidly attached to the standard f, and serves for holding matches, and at the same time its separate base becomes a resistance or collar7 against which the weighted foot is screwed in connecting the standard to the foot.

Within the burnertube d is the air-tube if, the parts being connected at the bottom to form an annular oil-space, as usual.

l is a tube sliding outside the airtube t', and having a bottom outward ange, l2. lt also 5 5 receives around it the stationary or capillary wick 3, which lits it tightly.

The ordinary tubular wick 4 tits over this capillary wick 3, and can be slipped up from time to time as it is consumed, and the up- 6o per end can be out oft' or the carbonaceous matter removed. To facilitate this operation l provide the tubular wick-case o, that is inside the burner-tube d, but outside the wicks. This case o is shown with inward ange 6 65 below the ange l2, so that the wick-tube l and wicks will be lifted by lifting the tubular case 0, and when this has been done the wick 4 can be raised by grasping it with the fingers acting through the openings at 7 in the 7o sides of the case o, and the tube l can be pushed downwardly within the wick to whatever extent is necessary, and then the wick is trimmed oit' level with the upper end of the ease 0. ,7

At the outer side of the case o there is a rib, s, and the thickened portion of the upper end of the burner-tube d is slotted to allow this rib to slide vertically in it.

The upper end of the wick-tube ldoes not 8o extend as high as the top of the air-tube il; hence if the wick-case and wick are raised the {ia-me will be increased by exposure of the inner surface of the wick at the upper end. To do this I provide a sleeve, r, that surrounds the upper part of the burner-tube d.

It has au inward flange at the top end, resting upon the upper end ofthe burner-tube. This iiangeis notched to pass down over the rib s, and this rib sis notched above the up- 9o per end of d, to allow the sleeve to he revolved afterit has been slipped down to place.

There is a stud, 8, on d, and the sleeve r is slotted vertically,so as to allow it to slip down past this stud, and there is au incline, 9, running downwardly, or an inclined slot in this sleeve 1^, so that when it is turned around i will be lifted by running upon this stud, and in so doing the flanged upper end will act in the notch of the wick-case rib s and lift the :cc

case and wick to increase the flame, or the reverse movement lessens the iiame.

It is often important, especially with burners that are used in chandeliers, to be able to ad# 5 just the flame or to extinguish the same from below. To provide foi` this I add tothe wicktubea cross-bar, 10, and use a tube, fv, that slides within the air-tube, s0 that its upper end can act beneath this cross-bar l() and raise the wick-tube and wicks to expose more of the inner surface of the wick above the upper end of the air-tube.

A pin, 22, at the side of the tube c, passing into the screw-thread at the lower end of the air-tube, serves to hold the tube o in its place, and also to raise andlower the same, and also to hold the drip-cup w in place, such cup w being` at the lower end of the tube fu.

To provide for extinguishing the light, I introduce the small tube u within the tube o, such tube u being open at the bottom end and extending below the drip-cup to receive the rubber ball t, that injects air when squeezed to blow the light out. rIhis tube u also can be used as a match-carrier for lighting the lamp from below, there being a cross-bar at 14 to preventthe match slipping down the tube when introduced at the upper end thereof.

The upper end of the air-tube t' is slotted for the cross-bar l0, and the lower end of the tube fv, within the drip-cup, is perforated for the air to pass into the air-tube.

I claim as my invention- 1. rIhe wick-tube l, stationary wick 3, wickcase o, and the flanges l2 and 6, in combination with the wick 4, burner-tube d, and airtube i, substantially as set'forth.

2. The combination, with the wick 4 and wick-case o, of the rib s upon the wick-case, the wick-raising sleeve r, incline 9, and the pin 8 on the burner-tube, substantially as set forth.

3. The wick-tube Z and wick 4, in combination with the cross-bar 10, tube '0, screw, and drip-cup, substantially as set forth.

4. The tube v, extending up within the air- 4 5 6. The combination, in a student-lamp, of

the burner-tube d, supply-tube c between the burner-tube d and the fountain, the rod attached to the tube c, the tubular standard f, into which the rod d passes, the weighted base, through which the standard f passes and into which it is secured, the collar e, surrounding the rod d and screwed into the top of the standard f, and the head2 upon the lower end of the rod d', to steady said rod d', and also prevent its being drawn out of the standard j', as set forth.

7. The combination, with the wick and its tube, of a wick-case surrounding the wick and having openings to give access to the wick, substantially as specified.

8. The combination, with the wick-case and its rib, of a wick-raising sleeve having an inward iiange at the upper end passing beneath the rib, substantially as specified.

.l. The combination, with the standardfand the weighted base g, of the match-cup 7c, surrounding said standard, and against the base of which cup the said weighted base is screwed, substantially as set forth.
